I RAZOR Application filed May 9, 1982. Serial No. 610,240.

This invention relates to razors, blade holders and razor blades, andmore particularly to razors and bladesof the safety type.

A primary object of this invention is to provide a razor wherein the,blade can be move freely and be tilted to any angle desired, to vary thefineness of the cut or shave, without loosening the parts which hold theblade in position.

Another object of this invention is to p ro vide a blade so constructedthat it possesses superior strength and resilience.

A still further object of this invention is to provide a safety razorwherein although the handle and associated parts are securely clampedtogether, yet the angle of the blade may be controlled and the edgesthereof move freely and be tilted without affecting the degree of suchclamping.

Still another object is to provide a blade holder assembly, consistingof a handle and two clamping members for holding the blade, and at leastone of said members havin a moveable carrier permanently mountedtherein, so that the carrier and member actually become one unit.

Yet a further object is to provide a safety razor and a blade of a typethat is'practical, durable and convenient in use, simple inconstruction, and economical to manufacture.

Other objects and advantages of the present invention will appear fromthe description thereof to follow, taken in connection with theaccompanying drawing, in which Fig. 1 is an assembled view of the razorand blade, embodying my present invention, partly broken away to showmore clearly the normal position of the blade.

Fig. 2 is a View similar to Fig. 1, but shows at the limit of adjustmentof the blade.

Fig. 3 is a cross-sectional'view on the plane indicated by the line 3-3of Fig. 1.

Fig. 4 is a side View of the top member of the assembly shown in Fig. 1;

Fig. 6 is-a plan view of the intermediate member upon which the blade isadapted to rest; 1

Fig. 7 is a plan View of the blade; Fig. 8 shows a detail ofthe carrier;

Fig. 9 shows one of the clamping members ang the carrier in assembledform as a unit, an

Fig. 10 shows a modified form of Figs. 1, 2 and 3. a

Referring to the drawing; 5 indicates a curved upper clamping member towhich is fitted a screw 6 having a base 7. The screw 6 and base 7 areprovided with a slot 8 for a purpose to be set forth hereinafter. Ablade 9 having an aperture 10, (larger in size than the base 7), isassociated with the member 5.

A bridge 10 divides said aperture 10 into two separate openingspositioned at each side of said bridge 10, said bridge is also adaptedto be positioned in the slot 8 of screw 6, thereby preventing therotation of said blade 9, the edges 11 of openin 10 being bent to oneside, so that they sli e smoothly over the threads 12 of screw 6 untilsaid opening 10 receives the base 7, when the blade is fitted on themember 5. A carrier 14 is mounted on the lower clamping member or plate15, the carrier having extensions 16 loosely fittedwithin slots 17 inthe plate 15, the outer ends of extensions 16 are struck down orexpanded by a suitable tool, as shown at 18 to prevent the separation ofcarrier 14 from plate 15. Carrier 14 and plate 15 thus actually becomesa single unit as indicated by arrow 15 (see Fig. 9). This unit 15' isthen placed upon the blade 9; an opening 19 in plate 15 permits screw 6to pass through it until said opening, 19 reaches base 7, at the sametime the bridge portion 20 of carrier 14 is being automaticallypositioned in slot 8 of screw I 6 and base 7, thereby preventing therotation I of said unit 15', and the upper surface 21 of the carrier 14engages the longitudinal central portion of blade 9 and bridge 10'.

The handle comprises a tubular member 23 provided with a threaded innerwall 24 and a reduced shoulder portion 25, a second tubular member-.26is snugly fitted over said shoulder portion 25. A cap 27 is looselyfitted over the end of member 26, a rod '28 extend ing through thehollow handle is carried by said cap 27, a portion of said rod 28 isprovided with a thread 29 engaginga second threaded inner wall 30 ofsaid member 23,

handle unit, members 5 and and blade 9 are assembled when the razor isprepared for use. v

Upon turning the cap 27, the rod 28 will be caused to travellongitudinally and the end 32 will move upwardly in slot 8 and engagethe carrier 14 at 33, pushing said carrier 14 and also the blade 9upwardly, the base 7 and lugs 5' are so arranged that they keep theedges of members 5 and 15 separated and apart from each other, thereforethe edges 0 said members .5 and 15 do not clamp the edges 9 of blade 9,and due to the space between said edges the edges 9 of said blade 9 arequite free and (during adjustment and flexing of said blade 9) may movefreely and be tilted, up or down, in'fact to any desired angle between.the edges of saidmembers 5 and 15 to vary the fineness of the cut orshave.

It will also be noted that due to the special structure of the blade,namely the bridge portion dividing the aperture into two separateopenings positioned at each side of the bridge, permits the longitudinalrun of the center portion of the blade to be intact, and this is ofgreat importance, because it is the intact center portion that gives thestrength to the blade and makes the flexing of the blade perfect and thecutting edge pow erful, whereas, if the center run of the blade ispunctured, then the base for the strength i of the blade is broken andthe rest of the blade is just a lifeless mess of metal, that iswhy manyof the present type blades are not satisfactory to the user.

Applicant is hereby pointing out the fact that only in a structure suchas ap licant shows and describes, wherein sufficient space or room isprovided between the edges of the upper and lower clamping members, canthe rincipal idea of adjusting the edges of thelade, without looseningthe clamping members, be utilized; as the edges of the blade can thenmove freely, in or out, up or down, in fact to any desired angle,whereas, if space is not provided between the edges of the i upper andlower clamping members, and instead the edges of I the blade are clampedtight between the edges of the clamping members, naturally when thecenterof the blade will be forced upwardly, the edges of the blade willnot move into any direction; furthermore, due to the brittleness in eachblade as a result of the temper, the edges or part of the edges willbreak off if they cannot,

on account of being clamped, move freely and be tilted.

' From the above it will be seen that I have provided a'constru'ction ofa few un1ts,nam'ely, a handle unit, a supporting plate unit and a--curved member (in fact equivalent to the 1 handle, supporting member andcurved member of the present known Gillette type)- which can be veryeasily adjusted, operated and used. And after the parts have beenassembled'and suitably tightened (by rotation of handle member 26 which,through screw 6, clamps upper member 5 and plate 15 together), theadjusting mechanism 27, 28

and 14 may be operated to vary and tilt the though the rod 28 iseliminated and cap 27 is stationary fitted to the handle. Or, forexample, the cap 27 may be threaded on to 1 the handle 26 and the rod 28suitably guided within the handle. a j

Although I have mentioned in describing my invention certain parts thatmay be used, of what material they may be made, and how theymay beconstructed, yet I desire it to be understood that various changes indetail and modifications may be resorted to without departing from thespirit of the invention.
